Abstract

Argon plasma etching of Bi₂Sr₂Ca₁Cu₂O8+δ (Bi-2212) IR- PLD grown films is reported. Etch rate as high as 0.35µm/min were measured, and were found to be dependent on argon discharge current during etching. EDX measurements showed that no significant variations in the film stoichiometry even at higher discharge currents. The transition temperature Tc did not deteriorate with plasma etching but increases with decreasing film thickness. Etch results indicates that the Argon Plasma Etching can be a viable technology for high Tc superconducting thin-film patterning.
